v1li nation of parts herein shown and described,

and more particularly pointed out in the claims.

In the drawings, wherein like reference characters vindicate `like orcorresponding Fig. 1 is a fragmentary horizontal section .through awindow, a plurality of weather strips embodying my invention being shownin connection therewith; and

Fig.- 2 is a fragmentary perspective view of the weather stripping shownin Fig. 1-

In the drawing, the reference character .10 is a window casing of anysuitable constructtion and adapted to accommodate an upper sash 11 and alower sash 12 of suitable construction. Oneredge of the sash 11 ridesbetween avstop-piece 13 and a partition strip 14. Likewise, one edge ofthe sash 12 rides between the partition strip 14 and a stop strip 15.Secured tothe casingA 10 and engageable by the sashes 11 and l2 are apluv nallty of weather strips 17 of substantially identicalconstruction, lo ne strip being provided i'or the sash 11 and anotherstrip being provided for the sash 12.

Each weather strip 17 is preferably formed from a strip of metal havino'some resiliency.

and comprises a flat portion 18 adapted to lie against the casing 10.One edge of the fiat portion 18 is folded back as at 19 to prof videsuperimposed layers of metal through which screws or nails 20 may bedriven to secure the weather strip to the casing 10. l The weather strip17 may be provided with Amediate portion 22 back along and away holes oropenings 21 to accommodate th screws or nails 20. The opposite edge ofthe `fiat portion 18 is also folded back to provide an intermediateportion 22 which contacts with a relatively small surface on the portion18, the remainder of the intermediate portion 22 being spaced from thefiat portion from itself. The leaf portion 24 is prefer'- ably arcuatein form so that it will not bite into its associated sash 11 or12. Theweather strip 17 associated with the sash 11 is shown in the form itnormally assumes when it is not compressed by the sash 11. The weatherstrip' 17 associated with the sash 12 is shown compressed by that sash,in which position it eil'ectually prevents a flow of cold air, dust,dirt or the like from the space between the sash and the casing. Havingthus described my invention, it is obvious that various immateriallmodifications may be made in the -same without departing `from thespirit of my invention; hence I do not wish to be understood as`limiting myself to the exact i'orm, construction, arrangement andcombination of parts hereinvshown and described or uses mentioned'.

What I claim as new and'desire to secure by Letters Patent is:

A weather strip formed of a substantially fiat metal strip having-oneedge bent over to lic on one face thereof. the other edge bent 35 overto form an intermediate portion having one edge lying latagainst thatface of the main strip onto which the first edge is folded, an outeryieldable leaf portion formed by bending the outer edge of theintermediate portion back along and away i'rom itself, and the extremeouter edge being slight- 1y curved away from the main strip to formaconvex bearing surface.y

In testimony whereof I have hereunto 95 signed my name.
